A Spectra Energy employee acknowledged to federal inspectors that
the company never conducted key tests for corrosion on a natural gas
pipeline that was already operating at excess capacity, according to
documents recently obtained by NaturalGasWatch.org.

There’s much more in the article, including this:

Additionally, according to another May 2, 2013 letter sent under
separate cover from (PHMSA) to Holeman, Spectra failed to install
equipment to monitor whether or not the natural gas pipeline in
question was being affected by corrosion and could not produce any
records indicating that the pipeline had, in fact, ever been tested
for corrosion or that the pipeline was even structurally sound.

So that’s what
“the pipe will be monitored 24/7” means.
Good to know.

See Item 2 in that
Final Order
with fines
from the
Pipeline Hazardous Materials Safety Administration (PHMSA)
to Spectra Energy CEO Gregory L. Ebel:

The Notice alleged that Respondent violated 49 C.F.R. §19 2.475 (b)
by failing, in two instances, to inspect the internal surface of removed
sections of pipe for evidence of corrosion.
Specifically, the Notice alleged that inspection reports indicated
Respondent failed to
inspect the internal surface of certain pipe sections for evidence of
corrosion, even though they had been repaired by welding in two full circumference sections of pipe.

Respondent did not contest this allegation of violation.
Accordingly, based upon a review of all of the evidence, I find that Respondent violated
49 C.F.R. §192.475 (b)
by failing, in two instances, to inspect the internal surface of removed
sections of pipe for evidence of corrosion.
